IPC: H05K3/46
Filed: 2001-11-19
Abstract: PROBLEM TO BE SOLVED: To reduce any electrostatic capacity to be generated between a through-hole and a ground layer and a power source layer. SOLUTION: A signal wiring 201a and a signal wiring 202a are connected by using a through-hole 402, and signal layers 203-206 of the through-hole are made irrelevant to the connection. Then, the parts irrelevant to the wiring connection are punched from the back face of a wiring board so that the parts can be removed by a drill which is larger than the diameter of the through-hole 402, and which is smaller than the through-hole clearance of ground wiring and power source wiring, in order to prevent the electrostatic capacity of the through-hole from being increased due to a ground layer/power source layer 302 and a ground layer/power source layer 303. The drilling position (X-Y coordinates) and depth (Z coordinate) are extracted from wiring design data.
